What is saw palmetto extract used for?

Saw palmetto extract is most commonly used for urinary symptoms associated with benign prostatic hyperplasia (BPH). It is also used by some people for hair loss related to androgenetic alopecia, though evidence is limited.

Does saw palmetto help BPH symptoms?

Research results are mixed, and many well-controlled studies show little to no meaningful benefit over placebo for BPH-related urinary symptoms. Some individuals still report mild symptom relief.

What is a typical saw palmetto extract dose?

A common studied range is 160–320 mg per day of standardized extract. Product strength and standardization vary, so follow the label and consider medical guidance for BPH symptoms.

What are the side effects and risks of saw palmetto extract?

Saw palmetto is generally well tolerated, but it can cause gastrointestinal upset, headache, or dizziness in some people. Seek medical evaluation for urinary symptoms to rule out other causes, including prostate cancer.

Does saw palmetto interact with medications?

It may interact with medicines that affect bleeding risk and with hormone-related therapies. If you take prescription medications or have upcoming surgery, consult a clinician before using saw palmetto extract.

Meta-analyses and recent clinical trials show mixed or minimal benefit for BPH symptoms; other uses lack strong clinical evidence.

Support for lower urinary tract symptoms due to BPH

Mixed

Saw palmetto may offer mild relief of urinary symptoms like frequent urination or weak flow associated with benign prostatic hyperplasia (BPH), but overall evidence is mixed and generally shows little to no clinically meaningful benefit over placebo.
